Firstly, edge extracting is conducted with a laplace operator for a k frame image of fk and a k-1 frame image of fk-1 collected by a camera; secondly, difference calculus is conducted for images of two frames whose edge is extracted, and a difference image of D is obtained; thirdly, average filtering and binary processing is conducted for the difference image of D, fourthly, the image which is processed of binary is judged, i.e. when the difference of a pixel in the difference image is more than the set threshold value, the pixel is confirmed as a target pixel; otherwise, the pixel is a static background pixel.
首先对摄像头采集的第k帧图像f k和第k-1帧图像f k-1分别采用laplace算子进行边缘提取,然后对经过边缘提取的两帧图像进行差分运算,得到差分图像D,然后对差分图像D进行均值滤波和二值化处理,最后对二值化后的图象进行判断,即认为当差分图像中某一个像素的差大于设定的阈值时,则认为该像素是目标像素,反之则认为是静止不动的背景像素。

A Prove that d/dx is a linear operator on V. b You can put a coordinate system on V by mapping p to p(0, p(1), p(2).(Please imagine that flipped 90 degrees so it is a column.) Find the matrix that represents d/dx in this coordinate system.
1证明d/dx是V上的线性算子;2你可以将p映射到p(0, p(1), p(2),从而给V加上坐标系(想象将其翻转90°,形成柱体),找出在此坐标系中代表d/dx的矩阵。
